Heel Shots

Hitting shots in the heel of the club or worse on the shank is caused by only 4 things. 

1.  Standing too close to the ball.
2.  Getting closer to the ball with your body during the swing.
3.  Swinging out too far with the club.
4.  The lie of the club is too upright or the length of the club is too long.

This list will help trouble shoot when you run across this mistake.  There might be characteristics of this mistake but these are the only reasons why you hit shots in the heel of the club.  So by the process of elimination you can isolate the mistake and start working on the correction.
